The GE/Bently Nevada 330905-06-10-10-02-05 is a 3300 NSv Proximity Probe engineered for shaft vibration and position detection in rotating machinery with tight installation constraints. This M10 x 1 threaded, unarmored probe delivers high-resolution measurements in applications where standard probes cannot physically fit due to counterbore, sideview, or rearview restrictions. The system comprises the probe, 1.0 meter dual-shielded miniature coaxial cable with ClickLoc connector, and Proximitor Sensor—designed to replace legacy 3300 RAM and 3000/7000-series 190 Transducer Systems.

## Key Features
• Compact 100 mm case length minimizes installation envelope
• ±0.1 mm accuracy for precision position and vibration measurement
• Dual-shielded ClickLoc cable eliminates RF interference
• Extended temperature operation from -40°C to 85°C
• IP67 sealing for harsh industrial environments
• Stainless steel construction resists corrosion
## Typical Applications
• Radial and axial vibration measurements on shafts under 51 mm diameter
• Axial position measurements on targets under 15 mm width
• Phase reference (Keyphasor) and tachometer signals
• Zero-speed position monitoring
• Centrifugal, refrigeration, and process gas compressors
## Compatibility & Integration
The probe operates with Proximitor Sensors requiring -17.5 Vdc to -26 Vdc at ≤12 mA. Output voltage ranges from -1 Vdc to -13 Vdc (gap voltage). Supply sensitivity is less than 2 mV change per volt input variation. Direct replacement for 3300 RAM and 3000/7000-series 190 systems.
